Cross-Platform Compatibility
The DCB206 is not compatible with DeWalt 12V MAX, 60V MAX FLEXVOLT-only tools (such as the DCB481 SDS Max rotary hammer), or any Milwaukee or Makita tools. It works in FLEXVOLT tools but at 20V MAX power output rather than 60V.
DCB206 vs DCB205 — Which Should You Buy?
The DCB206 (6.0 Ah) offers approximately 20% more runtime than the DCB205 (5.0 Ah) at the cost of slightly more weight (650g vs 585g). For high-draw tools like angle grinders or circular saws, the DCB206 is the better choice. For lighter tools like impact drivers, the DCB205 is often the preferred balance of weight and runtime.
